    Notes: Transition-Metal-Substituted Acylphosphines and Phosphaalkenes. XII. - Transition-Metal Sulfur Ylide Complexes, XXVIIzt - Conversion of a Phosphaalkenyliron Complex (η5-C5Me5)-(CO)2FeP=(SiMe3)2 into (η3-Phosphaallyl)iron Complexes by means of Me2S-(O)=CH2: Synthesis and Molecular Structures of Two Isomeres of (η5-C5Me5)-(CO)η5-P(CH-(SiMe3)2(CHC-0)}The transition-metal-substituted phosphaalkene (η5-C5Me5)-(CO)2FeP=C(SiMe3)2 (1) reacts with the sulfur ylide Me2S-(O)=CH2 (2) to afford the yellow η3-phosphaallyliron complex 4 with a syn-configuration in the organophosphorus ligand. In toluene solution at 40°C this complex undergoes an isomerization to the corresponding anti-configurated complex 5. Constitution and configuration of both compounds were elucidated by spectroscopic methods (IR, 1H, 13C, 31P NMR, and MS) as well as single-crystal X-ray diffraction analyses.

X-ray Analysis of the Diphosphetane The transition-metal-substituted diphosphene (η5-C5Me5)(CO)2Fe - P=P - Aryl (1) reacts with fumarodinitrile (2a) to give the 1,2 diphosphetane all-trans- as the result of a [2 + 2] cycloaddition. Similarly, compound 1 is converted by either dimethyl fumarate (2b) or dimethyl maleate (2c) into the same cycloadduct all-trans- (3b). Diphosphetane 3a was completely characterized by a single-crystal X-ray analysis.

    Notes: A series of new clathrate host molecules 1 - 8 containing two bis(diarylhydroxymethyl) groups attached to different positions (2,2′ or 8,8′) of a 1,1′-binaphthyl frame have been synthesized. Their clathrate formation properties with organic guests including alcohols, amines, ketones, and other dipolar aprotic compounds or aromatic hydrocarbons are reported (74 examples of clathrates) together with the results of solvent competition experiments for the parent host compound. The inclusion formation and the clathrate stoichiometries depend on the structure of the host molecules in a systematic manner. The crystal structures of the free parent host 1 and its pyridine clathrate (1 : 3) have been determined by X-ray diffraction. The molecular structure of the host is similar in the two species involving an intramolecular hydrogen bond between the host hydroxyls. No other hydrogen bond is involved in the free host case while in the pyridine inclusion compound the second host hydroxyl forms a hydrogen bond with the nitrogen of one pyridine guest which is surrounded by two unbound pyridine species such as to form clusters of three pyridine guests enclosed in the cavities between the host molecules. Thermal analysis corresponds with the two binding states of the pyridine molecules in the clathrate.

    Notes: Transition-Metal-Substituted Acylphosphanes and Phosphaalkenes, XXI.  -  Isophosphaalkynes as μ3-Ligands in Transition Metal ComplexesReaction of the μ-isophosphaalkyne complex (η5-C5H5)2 (CO)2(μ-CO)Fe2(μ-CPMes) (Mes = 2,4,6-Me3C6H2) (2a) with [(Z)-Cyclooctene]Cr(CO)5 or Fe2(CO)9 gives rise to the μ3-isophosphaalkyne complexes (η5-C5H5)2(CO)2(μ-CO)Fe2{μ-CP[M(CO)n]Mes} 3a [M(CO)n = Cr(CO)5] and 4a [M(CO)n = Fe(CO)4]. Similarly (η5-C5H5)2(CO)2(μ-CO)Fe2{μ-CP[Cr (CO)5]C6H2(CF3)3-2,4,6} (3d) is obtained. The metal carbonyl fragments are attached to 2 in a η1-fashion by the lone-pair at the phosphorus. In contrast to this the treatment of 2a with (Ph3P)2Pt(η2-C2H4) affords complex 5a in which 2a serves as an η3-3e ligand towards the PtPPh3 moiety. The molecular structures of 3a and 5a are determined by single-crystal X-ray analysis.

    Notes: Clathrate Formers with Allene Structure - Host Compounds, Crystal Inclusion, and Structure of a Dioxane ClathrateThe tetraaryl-substituted allenes 1-8 are synthesized, and their properties in crystal inclusion are determined. Dependent on the type and number of the substituents, host compounds result, which have different inclusion properties and clathrate selectivities. Host 1h forms inclusion compounds with a wide range of apolar and relatively polar cyclic guest solvents (26 inclusions altogether), while 2, 4, 5, and 7b form only one or two inclusions. In two-component solvent systems, high inclusion selectivities are found for the host compounds. The crystal structure of the 4.dioxane (1:1) clathrate is reported. Relations between structure and inclusion selectivity are discussed.

The chalcogene atoms are attached to the phosphorus atom of the ligand and do not participate in the bonding to the metal Equivalent amounts of 1 and Fe2(CO)9 lead to the phosphaalkenyl complex 6 with an Fe - C σ bond. On the other hand, a large excess of Fe2(CO)9 converts 1 as well as 6 into the cluster compound 7 featuring the bridging 1-oxa-4-phosphabutadiene ligand (η5-C2Me5)(CO)2Fe - C(O) - CH=P - CH(SiMe3)2. Constitution and configuration of all compounds have been elucidated by spectroscopic methods (IR, 1H, 13C, 31P NMR, and MS). In addition complexes 5 and 7 have been characterized by single crystal X-ray diffraction analyses.

    Notes: Rearrangements of the Metallodiphosphapropenes (η5-C5Me5)(CO)2FeP(SiMe3  -  P = C(R)(SiMe3) (R = SiMe3, Ph)Heating of a methylcyclohexane solution of (η5-C5Me5)-(CO)2FeP(SiMe3)  -  P = C(SiMe3)2 (1a) gives rise to the insertion of the P = C moiety into the CH bond of a ring methyl group with formation of the chelate complex η5-ηC5Me4CH2P-[CH(SiMe3)2]P(SiMe3)Fe(CO)2 (2) which is converted into the pentacarbonylchromium derivative [5-C5Me4CH2P[CH-(SiMe3)2]P(SiMe3)[Cr(CO)5]Fe(CO)2] (3). In contrast, a similar treatment of (5-C5Me5)(CO)2FeP(SiMe3)  -  P = C(Ph)(SiMe3) (1 b) furnishes the diphosphirane (5-C5Me5)(CO)2FeP  -  C(Ph)-SiMe3)  -  P (SiMe3) (5). By chromatography of its (CO)5Cr adduct 6, the P  -  Si bond is hydrolyzed to give the (diphosphirane)-chromium complex [(5-C5Me5)(CO)2FeP-C(Ph)(SiMe3)P(H)]-Cr(CO)5 (8). The molecular structures of 3 and 8 are determined by single-crystal X-ray analysis.

Treatment of 4a with excess of Fe2(CO)9 leads to the tetrahedrane [(η5-C5Me5)(CO)2FeP-PtBu]Fe2(CO)6 (6a) and the 1,3-diphospha-2-propanone derivative [(η5-C5Me5)(CO)2FePC(O)-P-tBu]Fe2(CO)6 (7a). Similarily, an analogous complex 7c is obtained from the reaction of in situ prepared (η5-C5Me5)-(CO)2FeP=P-C6H2(CF3)3-(2,4,6) with an excess of Fe2(CO)9.
